Incline Bench

I do 1 set with 70kg
using a very slow, proper form for 18–20 reps.
However, my 1RM
hasn't increased from 100kg for 2 years.
I'm avoiding increasing the weight out of fear of injury
and am focusing on increasing reps instead.
My reps have increased from 15 to 20.
Since I'm not lifting heavier weights,
it's obvious that my 1RM isn't increasing,
but I'm starting to wonder if it's a genetic limit.
I work out 5 days a week,
but at this point, I'm not even
expecting performance improvements;
I'll be happy if I can just maintain it haha.
